Problem With Shower

[ScottishGasMan]

Went to look at a mates shower tonight cos I thought the shower hose was loose and leaking, but foun there was a little clear pipe behind it gurgiling then p*ssing out water once the shower had been turned on.

can anyone tell me what this pipe is for? and what teh possible fault could be?

prd (pressure relief device) has activated.
most common cause. twisted hose withing the chrome hose, blocked showerhead.

you must find the cause before fitting new one as it will activate straight away.

These also activate when the waters been off, you have to open the stop tap really slowly. Phone triton for spares.

Ahh, thought it was somekind of pressure relife.

if I Untwist the hose or clear whatevers blocking it will the PRV still leak now its been opened? whats involved in changing them?

No its goosed once its gone, never changed one so dont know the ins and outs, but tennant in one house where this happened said it only took minutes to fix hers.

just remove the two outlet screws securing it to the tank and the prd behind will pull out.

its easy peasy.

good merchants should have them on the shelf. very common.
